CONTAINER FOR COLORING MATERIAL Filed Oct. 8. 1928 .Jhz/erztoraxPatented Nov. 12, 1929 UNITED STATES PATENT OFFICE WILLIAM M. STEELE, OFRIVER FOREST, AND EDWARD G. ALLEN, OF OAK PARK, ILLI- NOIS, ASSIGNORS T0JOHN F. JELKE COMPANY, OF CHICAGO, ILLINOIS, A CORPORA- IIION OFILLINOIS CONTAINER FOR COLORING MATERIAL Application filed October 8,1928. Serial No. 810,969.

This invention relates to a moisture proof container, more particularlyintended for containing and protecting material used for coloringoleomargarine and the like.

The device is particularly designed to be efficient as a container forsuch coloring material in fluid or powdered form, and it may be packedin a carton with the oleomargarine or other product with which it is tobe .used, without affecting the container or its contents.

One object of the invention is to so concellulose, a moisture proof,transparent material which is not affected by contact with the coloringmaterial to be contained therein, nor by contact with the oleomargarineor other product with which it may be packed for marketing purposes.

The lower plate member 3 is formed with a relatively deep dished portioncomprising a substantially flat, circular bottom wall 5 and an upwardlyand outwardly inclined wall 6. Extending outwardly and downwardly fromthe top margin of the wall 6 and integral therewith, is an annular ring7, terminating in a marginal flange 8, which may be horizontallydisposed as shown, or be slightly upturned.

As shown, the upper plate member 4 comprises a substantially flat,central, circular wall 9, slightly larger in diameter than the lowerwall 5 so as to function as a cover for the dished portion of the lowerplate 3 and extends to the upper margin of the inclined wall 6.Extending outwardly and downwardly from the top wall 9, the member 4 hasan annular ring 10 and flange 1 1 complemental to the parts 7 and 8,respectively, of the member 3. The top wall 9 is in a substantiallyhorizontal plane, somewhat above those complementally formed, connectedflange portions of the two plates. If the powdered coloring material isin the container in sufficient quantities, it is possible the top 9 willbe slightly bulged upwardly, but when the contents of the container is afluid, the top of the container will be substantially flat in itscentral portion.

The marginal portions of both plate members 3, 4, comprising the parts7, 8, 10 and 11, are securely connected together after the coloringmaterial has been placed in the member 3 by a cement indicated at 12.Preferably the cement used is ethyl lactate. Other cementing means maybe used, but we prefer to use one having the characteristics of ethyllactate.

By forming the I container members as shown, a chamber for the coloringmaterial is provided, and the connected marginal portions not only closethe chamber, but are so shaped and located relative to the chamber wallsthat same are reinforced and protected thereby.

It will be understood that to make the members 3, 4, the cellulose isshaped by the use of dies to form a plurality of lower members 3, thenthe coloring material 13 is placed in the dished portions thereof, andanother piece of cellulose is placed in juxtaposition to the lowermembers, and, after being shaped to form the parts 10, 11 for a luralityof plates 4, is connected to the parts l, 8 by the cement 12. Then theseparate containers may be cut in the octagonal form shown, or any otherdesired shape. Preferably a slight amount of heat is applied to thecellulose to facilitate the shaping of the plate members 3 and 4. g

The construction described is well adapted as a container for coloringmaterial in fluid or powdered form, because of the characteristics ofthe materials used therein and because of the form thereof. Thearrangement of the container is such that the contents are efiicientlyheld therein while the container members are being connected togetherand subsequently; and the marginal portions of the container are soshaped that a maximum Gil of contacting surfaces for connection witheach other is provided in a minimum of radial space.-

Obviously, changes in details of construction may be made withoutdeparting from the scope of our invention, and we do not intend to belimited to the precise form shown and described, except as pointed outin the appended claims.

We claim as our invention: Y

' 1. A container comprising a plate having a centrally dished portionand a downwardly and outwardly inclined annular ring integral therewith,a second plate having a substantially flat central portion sufiicient inarea to cover the dished portion of the first plate and a downwardly andoutwardly extending annular ring complemental to the ring of said firstmentioned plate, and means for connecting said complemental portionstogether.

2. A moisture proor' container comprising a bottom plate memberincluding a substantially fiat central portion and an upwardly andoutwardly inclined wall whereby a,

dished portion is formed, and an annular downwardly and outwardlyextending rmg integral therewith, an upper plate member havin asubstantially flat central portion slight y larger in area than the fiatcentral portion of the lower member, and a ring integral with saidcentral portion and complemental to said first mentioned ring, andcement for connecting said annular rings together.

3. A container made of cellulose comprising a plate having a centrallydished portion and a downwardly. and outwardly inclined annular ringintegral therewith, a second plate having a substantially fiat centralportion sufficient in area to cover the dished portion of the firstplate and a downwardly and outwardly extending annular ring complementalto the ring of said first mentioned plate, and a layer of ethyl lactatefor connecting said complemental portions together.

i. A moisture proof container made ofcellulose comprising a bottom platemember including a substantially flat central portion and an u wardlyand outwardly inclined wall where y a dished portion is formed, and anannular downwardly and outwardly extending ring integral therewith, anupper plate member having a substantially fiat central portion slightlylarger in area than the flat central portion of the lower member, and aring integral with said central portion and complemental to said firstmentioned ring, and a layer of ethyl lactate for connecting said annularrings together.

5. A moisture proof container made of cellulose comprising a bottomplate member having a substantially fiat central portion, a .wallupwardly and outwardly inclined from said central portion and anoutwardly extending ring integral therewith, and an upper plate membermarginally connected to said ring member of the first plate by a.
